The events and contributor plugins both monkey patched the `site` object. This worked fine when they were loaded once per site build, but with Jekyll 3.0 automatic site rebuilding in preview and watch modes, this applied the monkey patch recursively, causing the program to halt. With this commit, the monkey patching should only occur once per run.
